[Tarantool-patches] [PATCH v2 0/2] fiber.top(): minor fixup

[Serge Petrenko]

The first patch fixes variable initialization after fiber.top_enable()
so that cord clocks don't contain garbage on first event loop iteration after
enable.

The second patch alters fiber.top() test to wait for correct output before
testing it.

Branch https://github.com/tarantool/tarantool/tree/sp/gh-2694-test-fixup

Changes in v2:

  - push 0 instead of NaN when cord clock_delta_last is 0
  - review fixes as per review from Vladislav

Serge Petrenko (2):
  fiber: reset clock stats on fiber.top_enable()
  app/fiber: wait till a full event loop iteration ends
